c# - 在 Azure DevOps 中运行时，.Net/VS 测试运行器失败

Question

我正在运行针对 .Net Framework 4.6.2 的 C# 单元测试。

事情在本地运行良好，它也可以从安装在构建代理上的 VS2019 构建和运行所有测试。

但是，在 Azure DevOps 中运行构建时，使用托管或自托管代理，即使所有测试都成功，测试步骤也会失败。

运行 vstest.console.exe从命令行手动，在构建代理上，工作正常并成功。我使用与 Azure DevOps 相同的参数运行此命令。

日志产生的错误(数百个):

仅当“在发生灾难性故障时收集高级诊断”标志设置为 true 时才会出现此问题。 .

确保它关闭，然后它工作正常。

这个问题再次出现，即使我们将上述标志设置为 false。

我们这次找到的解决方案是在管道中添加一个工具安装程序步骤，并在测试步骤中使用它。
